Parts for the Audi A6 T

Known issues

Common issues with the C5 A6 include timing belt failure (leading to engine damage on the petrol engines *if not replaced on schedule*), oil leaks (especially valve cover gaskets and cam seals), suspension problems (control arm bushings, air suspension failures on some models), electrical glitches (instrument cluster failures, window regulators, central locking), and automatic transmission issues (slipping, harsh shifting). The 2.5 TDI diesel engine is known for camshaft wear.

WOF tips

WOF inspectors will scrutinize suspension components (especially control arms and air suspension), brake performance (including ABS), exhaust emissions, and oil leaks. Electrical faults can also cause WOF failures (e.g., malfunctioning lights or warning lights). Rust is generally not a major issue, but check around the windscreen and sills.

About the Audi A6 T

The C5 generation A6 is equipped with an impressive lineup of engines, including petrol variants ranging from the 1.8T up to the powerful 4.2 V8, along with diesel options like the efficient 1.9 TDI and the renowned 2.5 TDI. The luxurious interior offers an array of high-end features designed for comfort and convenience. However, as with any vehicle of this age, particular attention must be paid to common issues that can arise.
